Overview

The Keysight RP7982A regenerative power system is a single output, bidirectional, regenerative DC power supply with highly integrated safety features that protect both your people and your device under test (DUT). The regenerative capability enables the energy normally consumed to return to the grid cleanly, reducing energy consumption and cooling costs.

In addition, by combining the seamless source and load functionality into a compact 5U-high package, you save energy, floor space, and integration time. The RP7982A delivers a fast, accurate, and integrated regenerative power system.

The RP7982A is part of Keysight’s HEV/EV Power Converter Test Solutions that gives you the confidence needed to deploy high-voltage, high-power solutions to meet the fast-paced, high-growth demands of the HEV/EV market.

Reduce costs for cooling and electricity with an eco-friendly regenerative design

The regenerative capability of the RP7900 enables energy to be put back onto the grid cleanly, saving on costs associated with energy consumption and cooling while not interfering with the grid. When the RP7900 is sinking current either from rapid down-programming of the output or from discharging an energy source like a battery, it automatically returns the excess power to the grid.

The regenerative operation is automatic, so it requires no programming. To safeguard your DUT, the RP7900 provides “anti-islanding” that senses the grid is live before regenerating power back to it. With greater than 80% efficiency, the RP7900 helps you reduce energy consumption by using less electricity when sourcing or sinking and less heat dissipation, which lowers the air conditioning needed when sinking.

Additionally, the RP7900 provides clean regenerative operation by keeping the total harmonic distortion to a minimum of 2% (typical) at full load to minimize interference with other electronics.

Continuously source and sink current

The RP7900 can continuously sink up to 100% of its rated current for an indefinite time. The two-quadrant, bidirectional sourcing and sinking capability of the DC power supply allows for seamless, uninterrupted transitions between sourcing and sinking current without changing the power supply’s output characteristics or introducing disruptive behavior.

Accelerate test throughput with industry-leading specifications

Shaving seconds or even milliseconds off of test time can lead to significant savings for high-volume manufacturers, as throughput gains are a never-ending quest for test system designers. The RP7900 is a valuable tool for increasing throughput. It provides fast output speed, sub-millisecond command processing time (≤ 1 ms), and an output list capability that can help you achieve significant throughput gains in your testing.
